PHILIP O. DONNER, OF NEW YORK, N. Y.

MACHINE FOR CUTTING Fun."

SPECIFICATION forming part of Letters Patent No. 688,296, dated December 10, 1901. Application filed m 12,1901. Serial No. 68,038. (No model.)

To all whom it may concern:

Be it known that I, PHILIP O. DONNER, a subject of the Emperor of Germany, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Machines for Cutting Fur, of which the following is a specification.

My invention relates to machines forcutting fur, and has for its object mainly to provide mechanism for effectively and rapidly feeding the material to the knives or cutters and to prevent the clogging of the hopper through which the material passes on its way to the knives. I v

The invention will be fully described hereinafter and the features of novelty pointed out in the appended claims.

Reference is to be had to the accompanying drawings, in which Figure 1 is a side elevation of a fur-cutting machine with my improvements applied thereto. Fig. 2 is a plan thereof, and Fig. 3 is a sectional elevation of the upper part of the machine on line 3 3 of Fig. 2.

A is an elevator or other feeding device which conveys the material to the hopper B. This hopper is disposed at the upper end of the machine, and at the bottom of the hopper are located the knives or the cutting mechanism, which may be of any suitable construction, and, as shown, comprises a rotary knife 0 on a shaft 0, which rotates by means of a belt 0 from the pulley Den the main shaft D. E is the belt for driving the said shaft through the medium of the pulley D Within the hopper is arranged to reciprocate vertically, adjacent to one side, a plunger F, preferablyformed with a plate F,which flares upward and outward. The plunger F has two rods F moving in guides Gand having at their outer ends downwardlybent members F The lower ends of these members are connected pivotally at H with links or connecting-rods H, connected at their other ends with bars I. On one side of the machine the pin which connect-s the rod H and bar I is a crank-pin J on a disk J, mounted on a shaft J This shaft is rotated by means of gearwheels J K and a belt or cord L. In this manner a reciprocating vertical movement is imparted to the plunger F. Within the hopper is further mounted to reciprocate in a horizontal or, preferably, a slightly-slanting direction a pusher M, having an inclined apron or plate M extending upwardly therefrom, the said pusher having a stem M guided in stationary sleeves N. The pusher M is pivotally connected with two links 0, which are in turn attached to levers P, fulcrumed at P. The upper ends of .these levers are slotted and receive pins Q,'projected from slides Q, which move together with reciprocating rods R, having guided movement in stationary sleeves S and connected at R with the ends of thebars I. It will be understood that by this arrangement the pusher M and the plunger F will be operated in a certain relation to each other, and the parts should be so ar= ranged that the upward movement of the plunger will coincide with the inward move ment of the pusher, so that the following action will take place. The material dropping into the hopper and guided by the flaring plates F and M, which, as it were, form an auxiliary hopper, passes to the knives and is pushed downward by the plunger F, the pusher M receding from the plunger at that time, so as to allow space for the passage of the material to the knives. When the plunger moves upward, the pusher is projected inward to pack the material into the path of the plunger, and this action being repeated at-every stroke the material will be fed uninterruptedly and all danger of clogging the hopper will be avoided.

While I have described my invention as applied to fur-cutting machines, it is obvious that the construction described is applicable to other analogous cases where it is desired to feed a material liable to clog the hopper or other passage through which it is supplied.

I claim as my invention-- 1. The combination with the feed or hopper having stationary opposing side walls, of a plunger arranged to reciprocate vertically in the hopper, and a pusher arranged to reciprocatein the hopper between the stationary side walls thereof at an angle to the said walls and also at an angle to the path of the plunger.

2. The combination with a hopper or feed, of reciprocating material-feeding devices arranged therein, said devices being provided with diverging upward extensions forming together an auxiliary hopper.

3. The combination of a hopper or feed, of per at an angle to the plunger, levers fula plunger arranged to reciprocate therein, a cru med on stationary parts, links connecting usher arranged to reciprocate at an angle to said levers with the pusher,reciprocating rods he plunger in the hopper and upwardly-diwith which said levers are connected, and a 5 verging extensions secured to the plunger crank mechanism connected with said recip- I5 and pusher respectively and forming together rocating rods and with the pusher.
